![]() ![]() When you register, your Tresorit client generates a 160 bit cryptographic random salt, which, combined with your password, is iterated 10,000 times with PBKDF2-HMAC-SHA1. Account security with PKI: With Tresorit, your team members accounts are protected with a zero-knowledge authentication method.Due to the strength of Tresorit’s end-to-end encryption and security, breaking this protection would take several human lifetimes. Tresorit never transmits or stores files, encryption keys and user passwords in unencrypted or unhashed form. You don't have to notify your users about this incident. This way, no data breach is taking place, as only the unreadable data is leaked. As Tresorit doesn't store encryption keys and file contents in plain text on the server-side, even if hackers access your files they will not be able to read their contents. Unlike mainstream file sync services, Tresorit's built-in end-to-end encryption guarantees that even in case of a server-side breach, personal data stored in the cloud is secure from exposure. Tresorit uses HMAC-SHA512 with a random key for each different file, and encrypts local profile files in GCM mode, which provides the same security with higher performance. ![]() Tresorit clients apply a Message Authentication Code (MAC) to each file’s content, with a key known only to the user’s client and those they share the file with, but not by the server. Tresorit guarantees that the files' content cannot be modified without your knowledge, even if somebody hacks our system.
